patch to sysutils/u-boot-tools/Makfile
sysutils/u-boot-tools has been failing to build on powerpc64 for quite some time. Adding COMPILER:c11 to USES is necessary but not sufficient. Apparently the 'sandbox' functionality is not available on powerpc.
Over time, I have tried to learn how to disable the sandbox function, but get lost deep in the details of Kconfig. It's time to mark it BROKEN just to save time on the cluster builds for now.
